  1. -delta H products have less NRG than reactants
    products warmer
    requires less Ea - spontaneous reaction
    exothermic reaction
  2. +delta H products have more NRG than reactants
    products colder
    require more Ea
  3. measure of heat content
    enthalpy (H)
  4. NRG available to do work
    free energy (G)
  5. - delta G
  6. +delta G
  7. Ea
    activation energy (amt. of NRG needed to get a reaction going)
  8. photosynthesis type of process (catabolic/anabolic, endergonic/exergonic)
    • anabolic, endergonic
    • consumes energy to build complex molecules from simpler ones
    • needs NRG to take place
  9. cellular respiration type of process (catabolic/anabolic, endergonic/exergonic)
    • catabolic, exergonic
    • organic compounds break down into simpler substances
    • releases NRG
  10. purpose of cellular respiration
    to break down hydrogen atoms in glucose to get its energy
  11. 3-carbon molecule formed after glycolysis
    pyruvic acid/pyruvate
  12. first part of cellular respiration that yields a small amount of ATP, when glucose is converted into pyruvic acid
  13. molecule similar to NADP+, accepts electrons during redo reactions
  14. reactant(s) in glycolysis
